2015 reg TA 1.0, CVVT

Some oil sites say 5w20, some say 5w30, either provided its API SM spec, SM now superseded to SN.

What's the preferred grade?

The likes of Mannol blend both grades specific for Korean cars.

What does it say in your handbook have you checked?
I got a manual online and the preferred option is 5w20 with 5w30 if the former is not available. However on a majority of the oil sites, 5w30 is the preferred option despitee 5w20 being available by the same blender.

I'm merely curious what 1.0 TA Picanto owners are using in their car's engine.

My manual says exactly the same - 5W20 or 5W30. I prefer to use the 5W30 - just to my way of thinking a 5W20 is a bit too thin and is probably recommended more to achieve the highest possible official fuel economy figures. I'd especially use the 5W30 if you are not going on long trips, since over time you can dilute the oil with water that is the by product of the combustion process. Not so much a problem if you make sure you take longer trips but even so, my feeling is that longer term the slightly thicker oil is better.

Indeed, I've decided to use 5w30. A 5w20 may just get a bit too thin on a hot day. SCT blend both a 5w20 and a 5w30 for Korean brand cars in their Mannol oils but since we use a VW spec 5w30 in our cars, I'm going to use that. I queried using VW504.00/507.00 on a VW forum I use and was told 504.00/507.00 was preferred by some in engines that use VW508.00/509.00 0w20 oil and the 5w30 gives better protection.

Mannol 7713 is for Korean cars and 7715 is for VW.

Looks like the 7715 is more for diesels, being rated SAE CF and ACEA C3.

The 7713 is not rated for diesel engines.

Mannol's 7715 is a VW504.00/507.00 spec oil.

504.00 is a gasoline (petrol) engine specification.
507.00 is a diesel engine specification oil.

Both 504.00 and 507.00 are combined into to one oil blend and the oil is available as a 5w30 and a 0w30. We've had a 1.2 i20 running on the 5w30 for a couple of years and it runs as sweet as a nut.
